Writing 1,000 lines of C might be better than writing 500 lines of Ada
plus 1,000 lines of Ada binding.  But the argument degenerates from "too
compelling" to "too stupid" when one uses it to justify writing 6,000
lines of C instead of 3,000 lines of Ada and a KSLOC Ada binding.  (Is the
typical Ada binding even that big?)

The c2ada Web page at Intermetrics listed Python and some other things as
prerequisites.  Python downloaded and built as per instructions, and
seemed to work.  But all the other prerequisites failed to even build when
I followed their instructions.  Had to find one of them by Web search
because the hyperlink was stale.

But, you get what you pay for.  :-)
